Add-ons
Add-ons extend your base plan (product, variant, and feed limits). Most add-ons use monthly purchased credits on your subscription. Some add-ons also include usage charges on your Shopify bill when you go beyond the volumes included with your credits.
Manage everything from Subscription in the app:
- Plan — your base plan and purchased credits status
- Credit usage — a chart showing how credits are used per add-on
- Subscription options — change plan tier, purchased credits, and view the Add-ons list

How credits work
| Concept | What it means |
|---|---|
| Purchased credits | Credits you buy through your subscription. Set them under Subscription → Credits. They must cover your total add-on usage, or you may see a deficit on the credit usage chart. |
| Dedicated free credits | Free credits tied to a specific add-on in your shop policy. By default, new shops receive 10 free credits for Trackers only (not a shared pool for all features). |
| Shared “any” credits | Only if your shop or coupon policy defines a global any allowance. These are applied after dedicated free credits, in add-on order: GAD → Trackers → Server side tracking → Data sources. |
| Credit usage chart | Per add-on bars showing: free credits used (green), purchased credits used (blue), unused dedicated bonus (hatched gray), and deficit (hatched red) when purchased credits are not enough. |
| Minimum credits | The subscription form enforces a minimum number of purchased credits based on your current usage minus eligible free credits. |
Good to know
- Billing “on” vs actually in use: Approving an add-on in Shopify does not always mean it is fully configured. The add-ons checklist and credit chart reflect real usage (for example, Server side tracking requires a server GTM container).
- Trackers: Credit cost depends on tracker type. Your first GA4 tracker may qualify for a one-time free-credit discount.
- Purchased vs free “any”: Only credits listed under
anyin your policy are shared across features. Default shops do not get 10 generic “any” credits—the default is 10 dedicated tag (Tracker) credits only.
Usage charges
Some add-ons include a usage allowance with your credits. If you exceed that allowance, Shopify bills usage charges (shown on the subscription approval screen and on your app bill). Each usage line has a monthly cap where noted.
| Service (on Shopify bill) | Rate | Add-on |
|---|---|---|
| Automated discounts usage | $1 per 1,000 Google Automated Discount ad clicks (product page visits) | URL integration (GAD) |
| Server side tracking usage | $1 per 100,000 server-side tracking requests | Server side tracking |
| Extra refreshes | $0.03 per 1,000 feed products per extra scheduled file-feed run | Extra feed schedules |
| Extra renewals | $0.30 per 1,000 feed products per extra renewal cycle (30-day basis) | Extra API feed renewals |
Usage lines are typically capped at $300 per month per line item.

Approval and troubleshooting
When activating an add-on, Shopify may show:
- Plan upgrade — if you are on a free base plan and the add-on requires a paid plan (common for extra schedules and renewals).
- Usage charge approval — terms for the relevant usage line.
- Credits to purchase — how many purchased credits you need to add.
Common issues
| Symptom | What to check |
|---|---|
| Add-on shows “not in use” but you enabled billing | Finish in-app setup (e.g. SST needs a server container; GAD needs Settings → Google). |
| Red deficit on the credit chart | Increase Purchased credits on Subscription to cover usage. |
| Subscription update fails on a free plan with feed add-ons | Upgrade base plan to at least 1,000 products before adding extra refresh or renewal usage. |
